I tried to follow just the first part of this guide:
http://talk.maemo.org/archive/index.php/t-39879.html
to make only the hello world part work. It doesn't
here is the error
Traceback (most recent call last):
File "helloworld2.py", line 69, in <module>
mainWindow = MainWin(None, "main window")
File "helloworld2.py", line 49, in __init__
self.setupUi(rootWidget)
File "helloworld2.py", line 25, in setupUi
MainWindow.setCentralWidget(self.centralwidget)
AttributeError: 'QWidget' object has no attribute 'setCentralWidget'
Should this be working(after tweaking), or should I go a whole different route?
If it should be working, what are the things to do to troubleshoot?
Here are the ingredients of the .py file. I'm not sure I have it entered into here correctly, I'm not sure I understand the correct way to enter it, so it will appear the same as in the file. If this doesn't look right I'll try again.

I refer to the article1 to build my GUI by PyQt5,The difference between the program of the article and mine is the module <img_controller.py>. When I initilize my img_controller instance,I only need the parameter ui(the class I got from Qtdesigner)and my program ,img_controller. will revise the attributes of ui. Initialize the parameters of img_controller.py according to 1 are directed inputted attributes of ui.
When I run the program got from 1, it can work normally; but I run my program, I can't get the mainwindow and the wrong message hints that "AttributeError: 'Img_controller' object has no attribute 'ui'".I don't know where is my problem, because in the function __ init __ of Img_controller(class), I state that "self.ui = ui",anyone can tell me the problem, thank you very much.

What you DIDN'T say was the key piece of information -- the rest of the traceback. Notice that Img_controller.__init__ calls self.read_img, which calls self.set_img_ratio, which calls self.__update_img, which uses self.ui, and that all happens BEFORE you set self.ui. You need to swap the order of that initialization.
I'm having this problem and I have no ideea why is not working.

I think the issue is this: self.browseBtn.clicked.connect(self.browseBtn).
You are trying to connect the click event to the button itself.
You probably want to do something like: self.browseBtn.clicked.connect(self.method_to_call_when_clicked) where method_to_call_when_clicked is replaced by the name of the method you wish to call when it is clicked.
An example already in your code is:
self.test_2.clicked.connect(self.open_test_window)
I have two windows, first window is 'FirstWindow' and second is 'Calendar'. first window has one push button (pbSelectDate) and one label (lbDate). calendar window has calendar (CalendarBox) and one push button (pbSelect).
when i click select (pbSelectDate) from first window, calendar window pops up. I select the date and press select button (pbSelect) in the calendar window. i want to print the selected date to the label (lbDate) in the first window.

I am trying to build simple FTP client in Python and for GUI I use PyQt5. Problem is when I run program QTreeView do not showing directories, it is just blank surface. How can I code this to show folders and how to link with this listView below? I was looked on Google but I can not resolve this.

How do you want the QTreeView to show something if it does not tell you what to show?, a QTreeView what it does is show the content of some model, in your case you should use a QFileSystemModel.
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
...
class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setupUi(self)
model = QtWidgets.QFileSystemModel(self)
model.setRootPath(QtCore.QDir.rootPath())
self.treeView.setModel(model)
self.treeView.expandAll()
self.treeView.setRootIndex(model.index(QtCore.QDir.rootPath()))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())
